Although Subversion does not support committing to different locations at once, Syncro SVN Client offers this functionality regarding external items.
If items to be committed belong to different external definitions found in the
working copy, they are grouped under the corresponding item that indicates their repository
origin. Each parent item is rendered bold and its corresponding repository location is
presented when hovering it. Parent items are decorated with a small arrow ( 
) if they are
external definitions. The working copy root directory is never decorated and is
not presented if there are no external items listed (all items belong to the main
working copy). Each child item is presented relative to the parent item.
) if they are
external definitions. The working copy root directory is never decorated and is
not presented if there are no external items listed (all items belong to the main
working copy). Each child item is presented relative to the parent item.Note: When
an external directory has modifications of its own, it is presented both as a
parent item and as an item that you can select and commit. This is always the case for
external files.
The sets of items belonging to external definitions from the same repository are
committed together, resulting a single revision. So, the number of revisions can be smaller
than the number of externals. External definitions are considered from the same
repository if they have the same protocol, server address, port, and repository address within
the server.
Note: External files are always from the same repository as the parent
directory which defines them, so they are always committed together with the changes from
their parent directory.
